Zinnia marylandica 'Zahara Starlight Rose'

Truly spectacular 2010 AAS award-winning bedding plant! The pretty white flowers with an attractive pinky-rose centre are 6cm (2.5in) across when fully open. Bushy, dwarf plants flower freely and are so tolerant of such conditions as heat, humidity and drought that they were planted extensively in floral displays at the Beijing Olympics.

Non-stop-flowering Zinnia Zahara Starlight Rose follows on from the success of Zahara Yellow and will similarly attract beneficial insects, such as butterflies, to the garden. A real 'must' for borders this season!
